Entanglement is a key ingredient for quantum technologies and a fundamental signature of quantumness in a broad range of phenomena encompassing many-body physics, thermodynamics, cosmology, and life sciences. For arbitrary multiparticle systems, entanglement quantification typically involves nontrivial optimisation problems, and may require demanding tomographical techniques. Here we develop an experimentally feasible approach to the evaluation of geometric measures of multiparticle… 
Witnessing entanglement without entanglement witness operators
The proposed method is remarkably simple: multipartite entanglement is witness without relying on the tomographic reconstruction of the quantum state, or the realization of witness operators, and is robust against noise and decoherence occurring after the implementation of the parametric transformation.
Accessible bounds for general quantum resources
A general framework that provides quantitative lower bounds to any resource quantifier that satisfies the essential property of monotonicity under the corresponding set of free operations is described.
Quantifying necessary quantum resources for nonlocality
Nonlocality is one of the most important resources for quantum information protocols. The observation of nonlocal correlations in a Bell experiment is the result of appropriately chosen measurements

Spatial entanglement of bosons in optical lattices.
This work adopts recently developed approaches for the determination of rigorous lower entanglement bounds from readily accessible measurements and applies them in an experiment of ultracold interacting bosons in optical lattices of ~10(5) sites, constituting the first rigorous experimental large-scale entanglements quantification in a scalable quantum simulator.
Geometric measure of entanglement and applications to bipartite and multipartite quantum states
The degree to which a pure quantum state is entangled can be characterized by the distance or angle to the nearest unentangled state. This geometric measure of entanglement, already present in a
Scalable multiparticle entanglement of trapped ions
The scalable and deterministic generation of four-, five-, six-, seven- and eight-particle entangled states of the W type with trapped ions are reported, which obtain the maximum possible information on these states by performing full characterization via state tomography, using individual control and detection of the ions.
Quantitative verification of entanglement and fidelities from incomplete measurement data
Analytical solutions as well as numerical methods are provided that may be applied directly to experiments, and the obtained bounds are compared with results from full-state tomography for simulated data.
Quantifying tripartite entanglement of three-qubit generalized Werner states.
Multipartite entanglement is a key concept in quantum mechanics for which, despite the experimental progress in entangling three or more quantum devices, there is still no general quantitative theory
Practical Entanglement Estimation for Spin-System Quantum Simulators.
Practical methods to measure entanglement for quantum simulators that can be realized with trapped ions, cold atoms, and superconducting qubits are presented and a single observable whose expectation value serves as a lower bound toEntanglement and that may be obtained by a simple quantum circuit is identified.
Hierarchies of geometric entanglement
We introduce a class of generalized geometric measures of entanglement. For pure quantum states of $N$ elementary subsystems, they are defined as the distances from the sets of $K$-separable states

This work provides a simple procedure to quantify Greenberger-Horne-Zeilinger–type multipartite entanglement in arbitrary three-qubit states and establishes a close link betweenEntanglement quantification and entanglements detection by witnesses.
When are correlations quantum?—verification and quantification of entanglement by simple measurements
The verification and quantification of experimentally created entanglement by simple measurements, especially between distant particles, is an important basic task in quantum processing. When
